SPECIFICATION forming part of Letters Patent No. 574,337, dated December 29, 1896.

Application inea May 29, i896.`

vania, have invented certain new and useful Improvements in Shoe-Machines, of whichA the following is a specification.

My invention relates to a new and useful improvement in machines for lasting shoes, and has forits object to so construct such a machine as to render the operations of lasting a shoe entirely automatic and to so facilitate this work as Yto greatly increase the capacity of such a machine, thereby rendering the cost of labor. upona shoe very small.

With these ends in view my invention consists in the details of construction and combination of elements hereinafter set forth and then specificallydesignated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, I will describe its construction and operation in detail, referring to the accompanying drawings, forminga part of this specification, in which- Figure l is a plan view of my improvement showing a shoe in position to be operated upon by the several mechanisms of the machine; Fig. 2, a section at the line x t of Fig. 1'; Fig. 3, a section at the line yy of the same ligure; Fig. et, an enlarged detailed section upon a portion of the line of: xof Fig. 1, showing one'of the clamps in contact with the leather of the shoe and one of the stretchers drawing thereon; Fig. 5, a similar View after the st-retcher has been turned in position by one of the folders; Fig. 6, a section at the line .e z of Fig. 1, showing the mechanism for drawing the leather into shape upon the shank of the last; Fig. 7, a similar view illustrating the position of this mechanism when acting upon the leather; Fig. Y S, a section at the line o n of Fig. 1, showing one of the crimpingtools; Fig. 9, a plan view of the folding mechanism at the toe portion of the machine; Fig. 10,v a sectional elevation of the clamp for holdingthe last in position and the clutch mechanism for holding and releasing said clamp; Fig. 11, an enlarged detail section of the jaws of one of the stretchers; Fig. 12, a section at the line n u of Fig. 11; Fig. 13, a

detail of the operatiiig-tables and cams for actuating the same, and Fig. 1t a similar View of the power-shaft and worm-Wheel and worm for transrnittingmotiou from said shaft to the cam-shaft and also showing the clutch mechanism for stopping and starting the cam-shaft.

Referring to the drawin in detail, 1 represents the frame o f the machine, which maybe of any suitable construction to support the operating parts thereof, and projecting upward from the top of this frame are two posts 2, so arranged relative to each other as to height and position to receive the last, as clearly shown in Figs. 1 and 2, and the last is clamped in position upon these posts by thepresser-rod 3, which is guided within the housing 4, said housing being moun ted upon the bracket 5, which in turn is support-ed by the frame of the machine. rlhepresser-rod has coiled about it a spring G, the lower end of which bears upon the bottom of the housing, and the upperend is confined bythe collar 7, said collar being` secured to the rod and having formed therewith a handhold 8, the object of which is to enable the operator to depress the rod 3 against the action of its spring. A conical plug 9 is fitted in a correspondinglytapered hole in the top of the housing, and this plug is made in two sections, so that when it is drawn into the tapering hole the sections are closed upon the rod, thus clamping said rod, and this is accomplished by connecting with the plug a lever 10, as shown in Fig. 10, said lever being pivoted at 11 and connected by the rod 12 tothe lever 13, which latter in turn is connected by the rod 14 to the cam-lever l5, the end of which is arranged in the line of travel of a suitable cam, as will loe hereinafter set forth.

The first operation in lasting a shoe by my improvement is to secure the insole upon the bottom of the last 16 and draw the upper, which has been properly formed by stitching, as is well understood, over the last, then place said last upon the posts 2 and clamp it in position by drawingdown upon the presserrod which will be prevented from releasing its hold upon the last by the action of the spring 17 upon the lever 13. When the last has thus been placed, the next operation is to stretch, clamp, and fold the leather in posi- ICO tion, which is accomplished by the following meehan ism:

A series of clamp-bars 1S are arranged radially about the end of the machine that cor responds to the top of the shoe to be lasted, and these bars are adapted to slide in suitable ways lt), supported upon the uprights 20, carried bythe frame, and motion is imparted to the clamp-bars by a series of bell-cranked levers 21, pivoted at 22 to the bars and at 23 to the uprights, and the levers are in turn connected by rods 2l to the table 25, which has a vertically reciprocatil'lg movement, brought about in the manner hereinafter set forth. Thus when this table is elevated the clamp-bars will be forced inward against the last or upper placed thereon.

26 is also a vertically-reeiproeating table arranged next above the table 25, and still above this is arranged a table 27, also having a vertically reciprocating movement, and upon the last-named table are mounted a number of tubes 2S, which support at their upper ends the stretchcrs 29, consisting of a stationary jaw 30 and a swinging jaw 3l, the latter being pivoted at 32 tothe former. The stationary jaw of each of these stretchers has formed therethrough a hole 33, adapted to receive the nose 34C of the spring-actuated toe 35, 3U being the spring for actuating the same. Formed with the lower end of the swinging jawl are slotted arms 37, in which fits a pin 3S, projecting from the sides of the head 39, which latter is carried by a rod 40. Each of these rods extends downward through one of the tubes 2S, and is given an upward tendency by the spring l1, which is coniined between the collar i2 and the ring i3, set within the tube. Each of the rods extends downward through one of the yokes al, the latter being mounted upon the table 2U, one upon either side thereof.

Coiled around the rods t() are springs i5, which are confined between the yolies, and the nuts 4b' run upon the ends'of said rods, the object being to form a cushion between the movements of the table 2G and the rods. The movements of the tables 2U and 27 are controlled by cams, as hereinaftersct forth, so as to iirst cause these tables to move away from cach other, which action will draw upon the rods l() and by the sliding of the pins 3 in the slots formed in the arms 37 will swing the movable j aw 3l toward the stationary jaw, and when this movement has been carried to a certain point the nose 3l will enter the hole 33, thus clamping any material which may have been interposed between said jaws.

In practice the stretchers are in their elevated position when the last is placed upon the posts and the jaws are distended so that the depending edges ofthe upper will fall within saidjaws. Therefore as themovementof the tables 2G and 27 take place,as before described, these depending edges will be clamped by the stretchers, and when this has been accomplished the tables 2G and 27 move downward in unison, by the action of their cams, and this will draw the leather tightly over the instep of the last. During the movements of the last-named tables the table 25 will also be moved upward, which will force the bars lb against the leather, for the purpose of holding it against retraction, and also in order that the leather around the edge ot' the last may be prevented from wrinkling when it is folded under.

The rods 24 are provided with sprin 47, in terposed between the collars 48 and the table 25, so that the forcing of the (.lan1pbars against the last will be cushioned. A series of folding-bars t9 are'arranged immediately beneath the clamp-bars and are adapted to be forced inward by the levers 50, which are pivoted at 5l to the uprights 2O and connected to said bars by projecting within the openings 52.

rlhe end of each of the bars i9 is provided with toe-pieces 5o, so arrai'iged as to fold the depending edges of the leather beneath and against the bottom of the last, as clearly shown in Fig. 5, when the bars t9 are forced inward, and this takes place just after the stretchers have released their hold upon said leather. The levers 50 are connected with the levers 5t by the rot s 55, and thelast-named levers are bell-cranked and are pivoted at 50, the vertical members thereof extending within the line of travel of a series of cam projections 57, arranged upon the disks 58, it being understood that there are two sets of these parts, one set for operating upon the toc of the last, and one set for operating upon the heel thereof. After the depending edges of the upper have been drawn down and clamped by the bars 1S itis iirst necessary to crimp these edges before permittin g the folder to act thereon in order to prevent the irregular overlapping of the leather,which would prevent a smooth surface from being formed, to which the sole of the shoe is to be attached, and this I accomplish by providing what I call the cri1npingbars" 5f), one arranged between each of the clampbars and carrying at their inner ends crimping-tools GO, which taper toward a point, as clearly shown in Figs. l and t), and these bars are guided in suitable bearin in the upright-s Gl and are actuated by the levers G2, the latter being pivoted at (53 to said uprights and connected by rods Gat to the table 25, so that when said table moves upward to force the clamp-bars 18 inward against the leather the bars 5!) will also be forced inward, and these movements are so timed that the clamp-bars will first come in contact with the leather and, on account of the intervening springs 47, will be permitted to dwell while the crim pin g-tools are still being carried inward, which will fold under a narrow section of the depending leather just prior to the action of the folders 49, which latter will fold inward the remainder of the depending leather. These movements of the several mechanisms will cause an even crimping of the leather about the toe and heel of the last, thereby forming a comparatively IOO IIO

smooth surface to which the sole of the shoe may be afterward secured in the well-known manner.

In practice the several sections of the upper, such as the leather and lining from which the shoe is to be formed, are glued together around theirlower edges and glue also applied to the inner surface to a sufcient distance from the lower edge of said upper so that when the depending edges thereof are folded inward and brought into firm contact with the insole by the mechanisms just described these edges will adhere to said insole, and when the proper material is used for this gluing the last and material carried thereby may be removed from the machine and after the glue has set the last may be withdrawn from the partlycompleted shoe, the insole being released therefrom by the withdrawal of the temporary nails orp'egs which have been driven into the last for securing said insole thereto.

In order that the upper may, be drawn around the shank of the last, four rocking frames 65 are pivoted at 66 to the posts 67, secured to the upper portion of the frame, and, as will loe seen, two of these frames are arranged upon each side of machine opposite the shank of the last, and each of these frames is connected by a rod 68 with the table 25 and has a collar 69, secured thereon, between which and said table is interposed a coilspring 70. The nut 7l runs upon the lower end of this rod and prevents its withdrawal from said table. Thus when the table 25 moves upward, as before described, the upper ends of the frames 65 will be swung inward toward the last in unison with the movements of the clamp-bars and erimpers.

72 are two pairs of levers pivoted at 73 to a stationary bar 74,' which is supported by the frames 65, and to these levers are pivoted the parallel levers 75, having pivoted to their inner ends the shoe 76, which is so curved at 77 as to t the general contour of the shank of the last,.a coil-spring 78 serving to hold the parallel levers and shoe in the position shown in Fig. 6. Thus when the upper end of the frame 65 is swung toward the last the shoe 76 willcome in contact with the side of the shank of said last or the leather stretched thereon, and as the frame continues to move the levers 75 will be moved backward relative to said frame against the action of the spring 78, and this backward movement of these levers will cause the levers 72 to swing upon their pivotal points 73, thereby drawing the levers 75 downward, which motion will be transmitted to the shoe 76, causing it to draw the leather tightly about the instep of the last'and downward around the curve of the instep after the manner of hand lasting, it being understood that the four shoes carried by the tilting frames 65 operate in unison and with a like effect upon the parts of the leather with which they come in contact. As the shoes 76 are intended only to act upon the sides of the shank provision must. be made for the carrying of the depending portions of the leather under said shank in firm contact therewith in order that it may be glued to the insole, which is accomplished by the following mechanism.

The lever 79 is pivoted at SO to each of the tilting frames G5, so as to be carried by said frames, and to the upper end of this lever is pivoted at 8l a link 82, which in turn is pivoted at S3 to the lever 84, the latter being pivoted at S5 to the bar 74. A n arm 86 is also pivoted at 83 to the lever 84, and, extending forward, has pivoted thereto at 87 a shoe 8S, the upper end of which is curved to fit the generalcontour of the under portion of the shank of the last. The lower ends of the lever S4 and the shoe SS are connected by the link 89, which, in conjunction with the arm 86, causes the shoe 88 to move in unison and be maintained parallel with the lever 84.

The arm 86 extends outward and has pivoted thereto at 90 a bifurcated link 91, the lower end of vwhich is slotted at 92 and is attached to the tiltingframe 65 by the pin 93. Between the members of this link is located a spring 94, the upper end being attached to the pin 90 and the lower end to said pin 93, thereby holding the outer end of the arm in its normally-lowered position, which will hold the inner end thereof and the shoe 88 thereby in an elevated position.

95 is an extension of the lever 79 and has pivoted thereto at 96 the rod 97, which latter passes through an openin g 9S of sufficient size to have no effect upon said rod, which also passes through the table 27 and has coiled around its lowered end a spring 99, which is confined between the nut IOO and the lower surface of said table. Thus as this table moves downward, as before described, the rod 97 will be drawn therewith, which will spring the lever 79 inward, and this movement is so timed that it takes place after the tilting frame has been swung t0 the position shown in Fig. 7, which brings the shoe S8 into contact with the leather upon the last, and the inward movement of the lever 79 will cause the lever Set to also swing inward, thus carrying the arm S6 and link S9, whereby the curved surface of the shoe 8S will be drawn over the leather in firm contact therewith, by which said leather will be caused to assume the exact shape of the last at that point, as clearly shown in'Fig. 7.

The action of the spring 94 permits the shoe SS to adapt itself to the varying curve of the shank of the last, and the spring 99 serves to cushion the movements of the lever 79 so as not to bring undue strain upon any portion of the leather and also permit a continuance of the movement of the table 27 after the lever 79 has ceased to move. This last-named lever is returned to its normal position, when the table 27 moves upward by the spring lOl. In .the lower'portion of the machine is journaled the cam-shaft 102, having mounted thereon the worm-wheel 103, which meshes with the ICO IIO

IZO

worm 101, secured upon the driveshaft 105, and the latter is -provided with a clutch 10G, splined thereon and having suitable teeth formed upon its outer face for engagement with corresponding teeth upon the hub of the belt-wheel 10S. Thus when rotary motion is imparted to this wheel and the clutch is in engagement with the teeth upon the hub of said wheel the drive-shaft 105 will be revolved, which in turn will revolve the cam-shaft.

The several cams which bring about the operations of the mechanisms are secured upon this shaft so as to move positivelytherewith. 109 are the outside cams of this series, the contours of which are such as to canse the rolls 110, which bear thereon, to dwell through the greater portion of the revolution of the camshaft, when said rolls will be in their elevated position, and these rolls are journaled upon the lower ends of the supports 111, the upper ends of which are connected at 112 to the able 25, thereby impartinga reciprocating motion to said table for the purpose hereinbefore set forth.

113 are cam-disks having formed in one of their faces cam-grooves, in which lit the rolls 111,journaled upon the outer ends of the levers 115, which are pivoted at 11G to the frame of the machine, and to these levers are pivoted the supports 117, passing upward through the table 25 and connected at 113 to the table 26. The contour of these grooves is such as to bring about the desired movement of the table to properly time the mechanisms operated by said tables, as before described. In the inner faces of the disks 113 are also formed calngrooves in which fit the rolls 119, journaled upon the levers 120, similar in all respects to the levers 115, and these levers are connected with the supports 121, which pass upward and are secured at 122 to thc table 27, thus bringing about the proper movements of said tables for the operation of the parts carried thereby. The disks 58, from which project the cam-surface 57, as before described, are also secured upon the cam-shaft, and these disks are two in number, each having three cam projections, one series for the operation of the levers 5U, through the rod 55, which actuate the folding-bars for operating upon the toe of the last, and the other series are for the operation of the similar parts which bring about the movements of the folding-bars for acting upon the heels of the last.

The exact shape and arrangement of the cams and canrdisks are not essential for the operation of the machine, and I therefore do not wish to be limited thereto, as any mechanisms for bringing about the proper movement of the several operating parts of the machine may be used, and I therefore do not enterin to an exact detailed description of the shapes and movements of these several cams, the only essential being that they bring about the desired movements in the proper time. For

convenience in holding the fore part of the last in position upon the posts 2 I pivot a curved lever 123 at 124, so that when the nose 125 thereof is swung downward it will come in contact with the upper side of the forepart of the last, thereby holding it tightly in position during the operations thereon, and this lever is actuated by a rod 126, pivoted thercto at 127 and connected to the table 25, a spring 128 being interposed between the collar 129 and this table, so that when said table is moved upward, as before described, and the nose of the lever comes in contact with the last, a continuation of this upward movement ofthe table will not effecta further movement of the lever.

In a machine of this character it is essential that the mechanisms thereof for accomplishin g the several operations shall be brought to a positive stop at a given point automatically. This is accomplished by providing a rod 180, which is secured to the clutch by a collar 131, the rod being actuated in one direction by the spring 132 and in the oppo site direction by the lever 133, which is connected therewith by the forked end 134 being coniined between the collars 135.

The lower end of the lever 133 is bifurcated and adapted to embrace the circular head 13G, which head is formed with a bell-cranked lever 137, the latter being pivoted at 13S, its horizontal member terminating in a treadle 139. A latch 140 is pivoted at lll-1 to the frame of the machine and is provided with a nose 142, adapted to engage the stud 113, the latter projecting from the side of the bellcranked lever. Flins when the trcadle is dcpressed sufficiently to bring this stud within the reach of the nose of the latch the latter will spring into engagement with said stud by either gravity or a suitable spring, (the latter not being showin) thereby holding said bell-cranked lever in the position shown lin Fig. 14C, and during the movement of this le ver to the last-named position the upper end of the lever 133 will be swung forward, thus forcing the rod 130 against the action of its spring, thereby putting the clutch 10G into engagement with the teeth upon the hub of the belt-wheel 108. This, as before described, will impart the rotations of said wheel to the wornrshaft and through the worm and wormwheel to the cam-shaft, thereby actuating the several mechanisms of the machine, all of which are dependent for their movements upon the cams and cam-disks carried by the last-named shaft. Now the worm-wheel 103 has projecting from one face thereof a pin 11111, which, during the revolving of said wheel in the direction of the arrow, will come in contact with the inner end of the lever 145, which is pivoted at 138, and, projecting outward, terminates in a lug 116, adapted to come in contact with the under side of the horizontal member of the bell-cranked lever 137. The lever 14:5 is also connected to the latch 110 at 147, so that when the pin 144. strikes the inner end of the lever 145 and forces it downward the first effect will be to IOS IIC

Igc

disengage the nose of the latch from the stud 143, thereby releasing the bell-cranked lever, the upper end of which will be carried inward by the swinging of the lever 133, which will be brought about by the spring 132, and since the clutch is connected to the rod 130 it will be seen that said clutch will be disengaged from the beltwheel, thus permitting said wheel to revolve freely upon the worm-shaft without imparting motion thereto. This of course stops the machine unt-il the clutch is again engaged with the hub of the belt-wheel, which is brought about in the following manner:

Then the upper end of the bell-cranked lever is swung inward, as just described, the

' treadle is also elevated, and by depressing the same with the foot the upper end of the lever 133 will be swung inward, thereby restoring the clamp against the action of its spring in engagement with the hub of the belt-wheel, where it will be locked by the engagement of the nose 142 with the stud 143, as before described. This downward movement of the treadle will also carry with it the outer end of the lever 145, on account of the engagement of the bell-'cranked lever with the lug 146, thus elevating the inner end 'of the lever 145 into the eld of travel of the pin 144, in order that it may be again actuated by said pin in its travel for disengaging the clutch and stopping the machine. Thus it will be seen that the movements of the machine will at all times be arrested at the same point, and the mechanisms thereof for operating upon the shoe should be so limited as to be in their normal position or that best adapted for the reception of the last and the beginning of their operation thereon.

lf at any time occasion requires, the machine may bestopped at any point in its operation by depressing the outer end of the latch 140, so as to disengage the nose thereof from the stud, the result being the disengagement of the clutch from the hub of the beltrswing the lever 13 upward against the action of the spring 17, and this, through the rod 12, will swing the inner end of the lever 10 downward, and, as before described, this movement will depress the conical plug 9, thereby .freeing the rod 3, which will be Amoved upward by the spring 0. These movements are so timed that the presser-rod 3 is elevated just prior to the stopping of the machine, and as the nose of the lever 123 is also moved out .of contact with the last in unison with the elevation of said rod it will be seen that the last and shoe carried thereby may be removed from the machine in order that another may be substituted therefor.

If found necessary, the lever 149 may be pivoted at 150 and connected by a link 151 to the handheld 8, said lever carrying a weight 152 for the overbalancing of the presser-rod 3 and parts carried thereby.

In practice I prefer to so time the cam projections 57 as to cause the folding-bars to act upon the depending edges of the leather in pairs, as follows: The folding-bars located beneath the clamping-bars (designated by A) first move inward to act upon the leather and then outward, when those indicated by B will in turn act upon said leather, and finally those indicated by C. These successive operations upon the leather from different points have the elfect of following up the crimpingtools and more thoroughly folding the leather upon the insole carried by the last, the result being that the folds in the leather will be regular and evenly arranged, thereby presentiug a better surface for' the securing of the sole to the upper than would otherwise be the case. 'L

The ways 19, in which the clamp-bars 18 and the folding-bars 49 slide, are provided with loose bottoms 153, which have turned edges overlapping the sides of the uprights 20, so as to be movable thereon, and while the folding-bars are not in action their inner ends are held elevated by means of spring- .pressed buttons 154, secured in the uprights.

The toe-pieces 53 on the folding-bars have cam-shaped noses, which are so shaped as to be forced Vdownward when striking the last and carrying with them the clamping-bars and bottoms 153 against the spring action of the buttons 154, thereby drawing the leather tight around the contour of the last, but when the folding-bars and clamping-bar are withdrawn the buttons 154 force the inner ends of the bottoms 153 upward in position for the next stroke.

The various tools which operate upon the shoe are made adjustable and interchangeable, so that when a different form of shoe is to be operated upon these tools may be adjusted or others substituted therefor which will be especially adapted to the particular design of shoe beinglasted. Thus any style of shoe, and even mens and ladies slices, may be lasted by my improved machine with equal facility.

Many modifications might be made in the designing of the several parts which go to make up the operating mechanisms of my im- Ythe last, a series of clamp-bars arranged radiallyabout the heel and toe of said last, means for moving said bars to and from the IOO IIO

last, a series of folding-bars for turning the depending edges of the leather inward against the under surface ofthe last or insole carried thereby, a series of shoes 7G adapted to bear against the shank of the last, a series of shoes S8 to bear and move upon the surface of the last or the material placed thereon and means for bringing about the operation, subtantially as shown and described.
